Description

Description générale

Acetonitrile is a water-soluble polar organic solvent with exceptional solubilizing power, unique chromatographic properties, and ideal spectroscopic characteristics. [1]

Application

Acetonitrile is used as a solvent:

• To prepare mobile phase for LC/MS analysis of bioactive components in Graviola leaf extracts. [2]
• In Reversed-phase HPLC. [3]
• A solvent in chemical synthesis
• A solvent for sample preparation, including extraction, dilution, and dissolution of compounds prior to analysis.
